No Drawing.

To all 1071 am it may concern:

. Be it known that I, LLOYD S. GIBSON, a citizen of the United States, residing at Jamestown, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Artificial-lVood Compositions; and I do hereby declare the follovin to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to an artificial \vood compound. The object of the present invention is to provide a plastic compound adapted to be employed for artificial wood both as a substitute for Wood and other material and also for the repair of Worn and broken portions of articles constructed of WOOd such as furniture, floors and the like and to be Worked, handled and finished in a. manner similar to ordinary Wood.

It is also an object of, the invention to provide an artificial Wood compound of this character adapted to forln an eflicient cement for uniting various kinds of materials such as wood, metal, glass, stone and the like.

The composition consists of a mixture of plaster of Paris, ocher, preferably gray ocher, water-proof varnish, and formic acid and liquid drier may be added to the mixture to cause the compound to dry quickly.

In preparing the composition, I preferably use the ingredients in about the following proportions ;viz.,

Plaster of Paris 7 pounds Gray ocher 7 pounds ater-proof varnish 1 gallon Formic acid 1 fluid ounce What is meant by gray ocher isa ground impure clay that is grayish in color and sold in paint stores under the trade name of gray ocher. The ingredients may be varied in proportions to suit different requirements by reducing the amount of the plaster of Paris down to approximately one half of the amount specified and increasing the amount of the gray ocher in proportion. A similar change can be made-in-respect to the gray ocher which may be reduced in amount down to approximately one-half of the amount stated and the amount of the plaster of Paris increased in proportion. The amount of the varnish can also be" increased so that the compound can be spread on the'surface with a brush. The formic acid may be increased Specification of Letters Patent.

any amount up to one-third of that menshaped into any desired form.

tioned or diminished any amount to approximately one-third of that stated Without materially affecting the character of the compound except as to varying the durability and hardness of the products. The gray ocher forms a heavy and durable body in conjunction With the other ingredients. The purpose of the plastenof Paris is to cause the compound to set or harden quickly and assists in imparting to the composition the qualities of a cement. The gray ocher also gives durability to the composition and increases the Wearing qualities of the same While the Water-proof varnish serves as a binder to unite the ingredients of the composition to fix and permanently hold together the said ingredients and at the same time assist in rendering the composition Water-proof. The formic acid also increases the durability and. hardness of the mixture. The ingredients are thoroughly mixed and applied to the surface to be coated with a trowel, putty knife or other instrument. It may be pressed into holes, cracks and crevices and may be used to join parts of Wood, glass or metal. The compound can be built upon surfaces and molded or otherwise It can be molded into or upon molding strips or lumber and it can be fashioned into various ornamental as Well as useful articles. It can be built up in the room and carved into various shapes and designs. It is made thicker or thinner by using more or less of the varnish.

When applied to an old or uneven or slivery floor it will make the same smooth and as hard and durable as a hard Wood floor. It furnishes a durable and Waterproof coating or finish. When made into strips or lumber it can be Worked similar to ordinary wood and it will take a high polish as smooth as glass and may be stained, painted, varnished, "rained or otherwise finished It can be employed for filling up cavities to almost any depth and it not only will not rot but its hardness Will increase with age. It is antiseptic, and may be ad.- vantageously employed for mosaic Work and it is not affected by changes in temperature so that it may be worked in hot or cold Weather Without danger of it becoming either too thin or frozen.
